Holographic Description of 2-Dimensional Quantum Black Holes

Abstract

In this work we obtain and analyse a black hole solution on the 1-brane of the Randall-Sundrum II braneworld in the 3-dimensional BTZ black hole bulk. Interpreting the results in the light of the conjectured duality between d-dimensional quantum-corrected black hole solutions and black holes on the brane in the AdSd+1 braneworld, we have found that there exists a lower bound for the size of a 2-dimensional quantum black hole. At the end, we suggest that this lower bound could be an informon, i.e. a remnant of the quantum black hole the existence of which has been proposed in the literature as a possible solution of the black hole information paradox.
